Idiot alert

What am I doing wrong?
I activated my minis (my roamio was already activated)
I made sure my Rmio was setup online for video sharing..

But now neither mini can talk to the rmio they say Tivo DVR not found..

Heres my setup
Rmio in master bdroom connected directly to router via a 50ft ethernet cable

The minis are connected to a ethernet switch via 2 50ft ethernet cbls
The ethernet switch is connected to the router via a 2ft ethrnt cable

Is this OK?
